You can check to see if your cable provider offers an unbundled option of internet service only. Not all will do this, but some will. Even though DSL is not an option for you, a cellular modem might be, especially if know you already have good service where you live. Sprint, Clear, AT&T and T-Mobile all offer these type of modems. They are like cell phones, but they only provide data to your computer. If 4G is an option in your area, that will be much faster and will be the cheapest as you likely won't have a data cap.
